Question 2

First order reaction. Value of k? Concentration of A equation ? Half life equation ? What would the administration of the drug be like ? What would the graph look like ?

Answer 2

1/s
[At]=[Ao] x e^-kt or ln[A]= ln[Ao]-ke(t)
0.693/k
Proportional to amount/ percentage of drug remaining 
Curved negative slope

Question 3

Answer 3

1/Mxs

Question 4

Collision theory of chemical kinetics?

Answer 4

That the rate of a reaction is proportional to the number of collisions per second between the reacting molecules

Question 5

The rate of reaction in terms of the fraction of colliding particles having enough kinetic energy ?

Answer 5

Rate = f(fraction of effective collisions)xZ(number of collisions /sec)
